Everything functions except one critical feature: the zone cut-off. At the moment users can pan endlessly and the service area isn’t being respected, so requests come in from locations we do not serve. Your job is to dive into the current codebase, track down what is preventing the polygon- or radius-based boundary from activating, and deliver a clean fix that works consistently on both platforms. Once the bug is resolved, I need a short explanation of the change and a new build I can push straight to TestFlight and Google Play internal testing. Acceptance will be simple: if I open the updated app, attempt to place a pin outside the predefined service zone and the action is blocked with...

I already own the domain and now I’m ready to turn the concept into a fully functioning application that works consistently on the web as well as on iOS and Android devices. The core requirement is a single, maintainable code-base that can be deployed to: • Web (responsive and SEO-friendly) • iOS (App Store-ready) • Android (Google Play-ready) I’m flexible on the underlying stack—Flutter, React Native, or any other modern cross-platform framework is fine as long as the final experience feels fast, native, and polished. You’ll take the lead on setting up the project structure, hooking up any needed backend endpoints, and configuring build pipelines so that publishing future updates is straightforward. Deliverables • Source code in a vers...
I’m building a productivity-focused mobile app for Android and need a developer who can take it from concept sketches to a polished Play Store release. The goal is to give users an intuitive way to organise daily tasks, set reminders and monitor their progress, all while keeping the interface fast and clutter-free. You’ll handle the full Android stack—clean, well-documented Kotlin (or Java) code, Material-compliant UI, local data storage and cloud sync hooks so the app is ready for future integrations. I’ll provide wireframes, feature priorities and branding assets; you translate them into responsive layouts, implement the core logic, connect any required REST endpoints and set up push notifications. Deliverables: • Complete Android Studio project with readab...
I’m looking for a skilled Android developer to transform my concept, “1000askia,” into a fully functional mobile app. The first release focuses on a clean, stable build with in-app purchases implemented through Google Play Billing. Here’s what I need: • A native Android application written in Kotlin or Java, compatible with the current Android SDK. • Seamless in-app purchase flow (subscriptions or one-time unlocks, depending on what you recommend for best user experience). • A lightweight dashboard or admin configuration so I can add or adjust purchasable content without digging into code. • Polished UI that matches material design guidelines; wireframes or a quick prototype are available on request. • Source code, build instruc...
Je souhaite faire développer une application mobile centrée sur l’intelligence artificielle, inspirée d’Instagram mais offrant une expérience nettement plus poussée. L’idée est de proposer un réseau social orienté photo-vidéo où l’IA amplifie la créativité des utilisateurs tout en ouvrant de nouvelles possibilités de monétisation et de suivi de performance. Fonctionnalités clés attendues : • Filtres avancés pour photos et vidéos : génération et ajustement en temps réel grâce à des modèles de vision par ordinateur (style-transfer, correction d’éclairage, effets 3D, etc.). • Opt...

I’m launching an online school and need a complete platform—both a responsive website and a companion mobile app—that lets me teach live video classes. The classroom experience must include an interactive whiteboard, screen-sharing capability, and a live Q&A chat so I can engage with students in real time. Students have to be able to create an account, verify their email or phone, and sign in securely before joining a session. From there they should see upcoming classes, enter the live room at the scheduled time, and interact with the tools mentioned above. Deliverables • Website front-end and back-end ready for production • iOS and Android app built from the same codebase or native, as you prefer • Secure user registration and authentication flow...

I want to turn my current WordPress site into fully functional mobile apps for both the App Store and Google Play. The overall branding can stay, but the in-app layout needs to improve for small-screen use: • Navigation menu – simplify the hierarchy so users can reach the most important sections with fewer taps. • Homepage structure – reorder or redesign the hero section and featured blocks to highlight fresh content first. Once those two areas look and feel right, everything else can mirror the website. Deliverables I expect 1. Production-ready iOS and Android builds, created with the framework you prefer (WebView, Flutter, React Native, etc.) and signed for store submission. 2. Source code or project files (Xcode workspace, Android Studio project, or equiva...

I need an experienced developer who can take a mobile app from concept to App Store and Google Play release. The core requirement is that the same code-base (whether React Native, Flutter, Kotlin Multiplatform, or another robust solution) delivers a smooth, fully native experience on both iOS and Android. Here’s the high-level flow I have in mind: • Collaborate with me to refine the feature list and user journeys. • Produce Figma or similar wireframes so I can sign off on the UX early. • Build the front-end and any necessary back-end or API integrations. • Handle rigorous device testing, performance tuning, and App Store / Play Store compliance. • Package and submit final builds, then provide post-launch support for any critical fixes. Code must be...
I already run a fully-responsive brochure website in English and Arabic that serves only text and images. What I now need is a very light native wrapper that opens the existing site inside a WebView on both iOS and Android, with a few essentials layered on top: • Manual language selection must remain available exactly as on the site. • Push notifications have to be integrated and tested end-to-end (Firebase / OneSignal or your preferred solution) so I can broadcast updates to users. • All store-side tasks—building signed binaries, preparing metadata in English and Arabic, submitting, handling review feedback, and getting the apps approved—are part of the scope. • After publication, you will keep the apps up-to-date and compatible with OS changes for a...
